# The autotools eclass enables building of the apps that needs the latest autconf/automake.
#
# NOTES:
#
#    This eclass was made to bridge the incompadibility problem of autoconf-2.13,
#    autoconf-2.5x and automake-1.4x, automake-1.5x.  Most packages needs
#    autoconf-2.13 and automake-1.4x, but cannot work with the latest versions
#    of these packages due to incompadibility, thus when we have a package that
#    needs the latest versions of automake and autoconf, it begins to get a
#    problem.
#
#
# Commented Example:
#
#    The following is a commented template for how to use this eclass:
